Frizzle feathers in chickens is the result of a dominant allele. Practice crosses between different types of chickens, by completing Punnett squares.
Students practice assigning genotypes (PP, Pp, or pp) to different traits based on whether the trait is dominant or recessive. They set up Punnett squares, and determine the phenotypic ratios of the offspring.
In this activity, you will use popsicle sticks to model the process of gamete formation and the combining of sperm and egg to create offspring. Results of the simulation can then be compared to Punnet square expected results. Popsicles should be made in advance, the set contains a male and female set with the genotypes…
